If you ride all year round, or do a lot of work on your bike, then no doubt you get as frustrated as us by the crap quality of some standard fasteners. We know that manufacturers have to manage costs, but sometimes, they really take the piss.
The minute the clocks go back, every steel fastener on your bike turns orange. By the first frosty morning, half the brackets are so rusty that a stiff breeze threatens to reduce them to dust. And you only have to pass within two miles of some salt spilt outside a chippy for all the alloy bits to fur up.
